MIXED REFRIGERANT AND REFRIGERATING CYCLE APPARATUS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a refrigerant having more superior characteristics by solving problems of equipment wherein a pressure is increased and an ejecting temperature is raised when a mixed refrigerant of difluoromethane and pentafluoroethane is used for a refrigerating cycle apparatus.

SOLUTION: The mixed refrigerant obtained by mixing the mixed refrigerant of the difluoromethane with the pentafluoroethane, with propane having high nonazeotropic properties contains ≥65 wt.% propane based on the whole amount.
